2026 Toyota 4Runner MPG: Fuel Economy by Trim and Drive Mode

How does a body-on-frame SUV built for trails still post decent fuel economy? That is the question the sixth-generation 4Runner has to answer. Toyota dropped the old V6 for a turbocharged four-cylinder. Here is what the 2026 4Runner returns at the pump, across all nine grades, both powertrains, and every drivetrain.

2026 Toyota 4Runner MPG at a Glance

The short answer, before the full breakdown by grade.

EPA-estimated fuel economy figures are for comparison purposes only. Your actual mileage will vary depending on driving conditions, how you drive and maintain your vehicle, battery age/condition, and other factors.

The Standard i-FORCE Turbocharged Engine

Six of the nine 2026 4Runner grades start with the i-FORCE 2.4-liter turbocharged four-cylinder. It is rated at up to 278 horsepower and 317 lb-ft of torque, paired with an eight-speed automatic. Specs come from Toyota’s 2026 4Runner press release. Torque builds early in the rev range, which matters on climbs like the grade toward the Santa Ana Mountains west of Corona. The engine pulls steadily without forcing the transmission to hunt for gears.

Four grades come with rear-wheel drive as standard: SR5, TRD Sport, TRD Sport Premium, and Limited. In gas form, the first three are each EPA-estimated at 20 mpg city, 26 mpg highway, and 22 mpg combined. Four-wheel drive adds heavier traction hardware. That drops the rating to an EPA-estimated 19 mpg city, 25 mpg highway, and 21 mpg combined. The gas TRD Off-Road and TRD Off-Road Premium share that same figure.

Efficiency did not cost the 4Runner its capability. When properly equipped, the 2026 model tows up to 6,000 pounds. Toyota confirms that figure in its 2026 4Runner announcement. Capacity varies by build. Our 2026 Toyota 4Runner towing capacity guide breaks the ratings down grade by grade.

Maximum towing and payload capacity figures are based on properly equipped vehicles and vary by configuration. Do not exceed any weight rating. See your owner’s manual and the vehicle’s door-jamb label for specific capacities.

The Available i-FORCE MAX Hybrid

The optional i-FORCE MAX pairs that same 2.4-liter turbo with a 48-horsepower electric motor. The motor is built into the eight-speed automatic and draws from a 1.87-kWh nickel-metal hydride battery. Output rises to up to 326 horsepower and 465 lb-ft of torque. It is standard on the Platinum, TRD Pro, and Trailhunter, and available on the TRD Off-Road, TRD Off-Road Premium, and Limited. Every i-FORCE MAX 4Runner comes with four-wheel drive. Specifications per Toyota’s 2026 4Runner press release.

One question comes up more than any other: does that much torque demand premium fuel? It does not. Both the i-FORCE and the i-FORCE MAX are designed to run on regular unleaded gasoline with an 87 octane rating, so the hybrid’s extra power costs nothing additional at the pump.

The electric motor does its best work at low speed, filling in torque while the turbo builds boost. Whether you are loading beach gear for a morning at Bolsa Chica in Huntington Beach or working through Orange County traffic, that assist arrives exactly where a traditional SUV burns the most fuel.

EPA-Estimated 2026 4Runner MPG by Configuration

Every 2026 4Runner carries a 19.0-gallon fuel tank. Small differences in combined mpg turn straight into miles between fill-ups. The table below covers all nine grades and both powertrains.

Range comes from the 19.0-gallon tank and the EPA-estimated combined rating. Your actual range will vary. See the ratings at fueleconomy.gov.

Is the i-FORCE MAX Worth the Upgrade?

Many shoppers assume a hybrid badge means immediate fuel savings. On the 4Runner, that is not quite the story. The gap between a four-wheel-drive gas model at 21 mpg combined and a four-wheel-drive hybrid at 23 mpg combined is 2 mpg. That is real, but modest. Measured against the hybrid’s higher cost of entry, fuel savings alone take roughly a decade to break even at average annual mileage and typical fuel prices.

The case for the i-FORCE MAX is not the payback math. It is the extra 48 horsepower and 148 lb-ft of torque, which translate into effortless low-speed crawling and confident highway passing. Those are the things off-road drivers actually notice. The hybrid also earns the best city rating in the lineup, and its coverage runs well past the standard warranty.

2026 4Runner Warranty and Maintenance Coverage

Toyota backs every 2026 4Runner with the same core warranty. i-FORCE MAX models add coverage for hybrid parts on top of that. See Toyota’s electrified vehicle warranty for the full terms.

Frequently Asked Questions

Does the 2026 Toyota 4Runner require premium fuel?

No. Both the standard i-FORCE and the i-FORCE MAX hybrid are designed to run on regular unleaded gasoline with an 87 octane rating. Neither powertrain requires premium fuel to reach its rated output.

Which 2026 4Runner gets the best highway MPG?

The rear-wheel-drive SR5, TRD Sport, and TRD Sport Premium lead the lineup at an EPA-estimated 26 mpg highway. If highway cruising range is your priority, those non-hybrid rear-wheel-drive configurations are the most efficient choice.

What is the EPA-estimated fuel economy of the Trailhunter?

The Trailhunter comes standard with the i-FORCE MAX hybrid powertrain and four-wheel drive, and is EPA-estimated at 23 mpg city, 24 mpg highway, and 23 mpg combined. Its overlanding hardware has minimal effect on those ratings.
